EMBROIDERING-MAGHINE.

SPECIFICATION forming part of Letters Patent No. 498,925, dated June 6,1893.

Application filed January 14,1893. Serial No. 45 8,321. (No model.)

' To all whom, it may concern.

Be it known that I, GEORG BAUM, a citizen of the Republic ofSwitzerland, residing at Arbon, Switzerland, have invented certain newand useful Improvements in Embroidering-Machines, of which the followingis a specification.

The Heilmann embroidering machines now in use are generally constructedwith two rows of needle-clamps at each side of the fabric-holder andonly a small number are constructed with three or four rows; that is tosay, there are two, three or four rows of needle-clamps arranged aboveeach other at each side of the fabric-holder. The reason that machineswith two rows of needles are generally used is that the machines havingthree or more rows are too high and heavy to permit of easily operatingthe same. As the stroke of the carriage, that is, the distance that thethread is drawn out from the fabric, is about thirty-nine inches, athread of corresponding length is usually used. When the carriage ismovedfrom the frame in which the fabric is held the threads'are drawntaut, but during the return stroke of the carriage the thread is foldedone-half its length and the folded portion drops to form a loop, whichwhen the thread has its full length is about nineteen inches long anddecreases as the thread is consumed. Itis therefore necessary that therows of needle-holders should be separated at least twenty inches, andso on. It is thus evident that embroidering machines with. three andfour rows of needle-clamps must be constructed so high that it isdiflicult to operate them conveniently, and for that reason the moreconvenient and rapidly operating two-row machines are used.

The object of my invention is to build a machine that is provided withmore than two rows of needle-clamps at each side of the fabric-holderand yet does not attain an undue height, and I accomplish this byforming in-v termediary supports for the threads which prevent theforming of the long loops. At the same time the patterns produced arearranged closely to each other, and in addition to the two needle clamprows used heretofore two or more needle clamp rows can be arranged.

In the accompanying drawings, Figure 1 is a front-elevation of part ofmy improved embroiderin g machine. Fig. 2 is avertical transversesection through the same. Fig. 3 is a detail front view of parts of thesupports for the machine. Figs. 4 to 8 are diagrammatical views showingthe threads supported in different positions of the carriage in relationto the fabric-holder, and Figs. 9 to 12 are diagrammatical viewsrepresenting the various positions of the supports.

Similar letters of reference indicate corresponding parts.

The arms a connected with the two carriages A A carry the four needleclamp supporting bars I) b b 12 on which the clamps c are arranged inthe usual manner. At each end of each clamp supporting bar I) b b b, apusher plate at is arranged which can act on the sliding hook bars 6 e ee arranged at the opposite sides of the machine to slide on rods ff. Foreach two needle clamp-supporting bars one group of hook-bars c e e e isarranged at each side of the machine, and the hookbars at one side ofthe machine are connected with the corresponding hook-bars at the otherside of the machine by cords or wires g 9 g g g g g g,of which cords orwires the upper ones g g g g serve as supports for the embroideringthreads h, whereas all the lower cords or wires 9 of which several canbe arranged above each other or interwoven in the form of a net, servefor clamping or holding the loops formed bythe embroidering threads. Thehook-bars of each group are connected pusher plates d by chainsnwhichare omitted in the right-hand part of Fig. 2, for the purposes ofavoiding confusion. When the carriage is drawn from the fabric-holdingframe 0 the hook-bars and the. cords or wires connecting them, arearranged uniformly between the carriage and the fabric-holding frame,and thereby the embroidering threads are supported uniformly by thecords or wires 9 g g 9 When the carriage moves toward the fabricholdingframe the embroidering threads are still supported by the cords or.wires g g g g and cannot form loops of half their length but only loopsequal to half the distance between the needle end and the firstsupporting cord or wire g, between which the embroidering thread isfolded to form a loop as shown in with each other and with thecorresponding I Fig. 4. As the carriage continues to move toward thefabric 3 the pusher plates (1 strike the first hook-bars e and move thesame with their supporting cord or wire g toward the fabric .9, wherebythe embroidery threads supported by the wires g g are folded, as shownin Fig. 5; when the pusher plates 02 strike the second hook-bars e, thatpart ofthe embroidering thread between the supporting wires 9 g isfolded, as shown in Fig. 6. Then in the same manner that part of theembroidering thread between the supporting wires g g is folded, as shownin Fig. 7, and finally that part of the embroidering thread between thesupporting wire or cord 9 and the fabric sis folded, as shown in Fig. 8.This last loop rests upon the board or support is arranged adjacent tothe fabric. The embroidering threads h are now folded on aserpentineline and are not only supported by the upper rods g g g g but are alsoclamped between the wires or cords g arranged directly below the wiresor cords g g g 9 so as to prevent entangling of the several embroideringthreads. When the carriage is moved from the fabric, the reverseoperation takes place, as is illustrated by Figs. 9 to 12. As thecarriage is moved toward the fabric, the chains 1' form loops betweenthe several hook-bars e, and when the carriage moves from the fabric,that part of the chain between the pusher-plate d and the firsthook-frames e is first drawn taut, as shown in Fig. 9; then the firsthookbars e are drawn along with the carriage, then the chain between thehook-bars e e is drawn taut, as shown in Fig.16, then the secondhook-frames e are drawn along with the carriage, then that part of thechain between the hook-bars e e is drawn taut, as shown in Fig. 11, andthe hook-bars e are drawn along with the carriage, and finally thoseparts of the chain 1' between the hook-bars e e are drawn taut, as shownin Fig. 12, until finally all the parts are again in the position shownin Fig. 1.

It is evident that when the embroidering thread is Worked into thefabric, the stroke of the carriage decreases and only as many hook-barse e e e and their supporting wires 9" g g g are moved from each other asis necessary to support the threads. The rods f that support thehook-bars e 6 6 are supported by brackets f from the frame of themachine, and bearers f on the tracks m for the carriage, so as not tointerfere with the movement of the latter. The fabric frame 0 isarranged to hold a piece of fabric for each row of needlesin this casefour pieces, each piece of fabric being held on two fabric-holding rollsp, so as to permit of adjusting the same in the usual manner.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an embroidering machine, the combination, with a fabric-holder,and a carriage reciprocating toward and from said fabricholder, a seriesof movable supports for the loose embroidering threads between thecarriage and the fabric-support, substantially as set forth.

2. In an embroidering machine, the combination, with a carriage andembroidery support, of a series of sliding bars between said carriageand fabric-support, and flexible devices connecting said sliding bars,substantially as set forth.

3. In an embroidering machine, the combination, with a carriage andfabric-holder, of a series of sliding bars between the carriage andfabric-holder, which bars have top-pieces extending transversely underthe threads and supporting the same between the carriage andfabric-holder, and a series of threadholding pieces on said bars belowthe supporting-pieces, substantially as set forth.

4. In an embroidering-machine, the combination, with a carriage andfabric-holder, of a series of movable frames transversely to theembroidery thread, between the same car riage and fabric-holder, whichframe supports the embroidery threads and pusher plates on the carriagefor actingon said sliding frames, substantially as set forth.

5. In an embroidering-machine, the combination, with a fabric-holder anda carriage, of a series of track-rods at right-angles to thefabric-holder, a series of hook-bars sliding on said supporting rods,wires connecting said hook-bars, which wires run transversely to theembroidery threads, and below the same, and chains connecting theseveral hook-bars, substantially as set forth.

In testimony whereof I hereunto sign my name, in the presence of twosubscribing witnesses, this 8th day of December, 1892.

GEORG BAUM'.
